Configuring User Access to Virus Settings
If you allow user access to the Message Center, we highly recommend turning off
permissions to change virus settings. Otherwise, users may be able to turn off
virus scanning.
1. In the Administration Console, go to Orgs and Users > Orgs, and select an
organization from the list.
2. Under Organization Settings, click User Access.
3. On the User Access page, set Virus Settings to Read, or clear all the check
boxes to turn them off.
See “Enable / Disable Message Center Access” on page 135 for further details.
Virus Notifications
When a virus is quarantined, notifications to users can be triggered. These
notifications can be customized and the interval between notifications can be set.
In general, most users do not need to be notified when viruses are quarantined.
See “ Quarantine Summary & Notifications” on page 149 for more information.
Virus Outbreak Events
When a statistically significant quantity of virus messages is quarantined from an
IP, the Connection Manager can be configured to block the server as an attacker.
See “Automatically Blocking Attacks” on page 453 for details.
